IMPROVEMENT IN OIL-CANS.

Specification forming part of Letters Patent N0. 55,975, dated July 3, 1866.

` River, Bristol county, Massachusetts, have invented a new and Improved Oil-Gan; and I do declare that the following is a full, clear,

and exact description o'f the same, reference bei-ng had to the accompanying drawings, making a part of this specification.

Figure l is a perspective view of the oil-can. N N is the fountain. C is the cap upon the rod iu the air-inlet.' A is the shut-off, and T T the supply tube or outlet.

Fi g. 2 is a transverse diagram of the oil-can, Fig. l, in which A B is the shut-0H; X X, the drippingchamber; S, the spiral spring attached to the shut-off A B at p. C D is the valve-rod passing` through the air-inlet I I I, and attached to the shut-off rod A B.

Fig. 3 is the same repeated with the fount ain N N attached. l

In order to more fully explain this oilcan, I will illustrate its operation.

Supposin g the fountain N N to be filled With oil for use, now, if I desire to oil some object with a continuous stream of oil, I invert the can, press my linger upon the cap C, which pushes down the rod O D through the air-inlet I I I, at the same time withdrawing the shut-oftl A B through the opening O in the end of the supply-tube J J. By this means the oil in the fountain N N is allowed to flow copiously, the air passing into the fountain N N through the air-inlet I I I as it becomes emptied at O.

Now, if I desire to stop the flow of oil without inverting the fountain N N, I remove my fmgerfrom the cap C. Then, by means of the spiral spring S attached to the rod or shut-0E A B, the same is thrown up and into the opening O in the supply-tube J J J, while at the same time the air-inlet I I I, by means of the valve V attached to the rod G D, is closed, so that no air can pass in, and by the shut-oft' A B no oil can pass out. Y

Now, if I desire to let out oi' the supply-tube J J only a drop of oil, I take the oil-cau in my hand, and, without touching the cap C, I place the point A upon the obj'ect requiring the drop of oil and press it for an instant. The oil follows, and as soon as the pressure is removed from the point A by the force of the spiral spring S the point A is driven through the opening O, and the oil cut off and ceases to iiow.

If, by any means, the air-inlet or supplytube should become gummed up by oil, by removing it from the fountain N N it can easily be cleansed.

By reason of the chamberX X all oil which may accumulate in the air-inlet I I I will be secured and kept from flowing out of the inlet at its top, and when the can is returned to its proper position Wjll iiow back again;

What I claim, and desire to secure as my invention by Letters Patent, is

The combination of an air-inlet, I I I, supply-tube J J, dripping-chamber X X, spiral spring S, shut-oft' rod A B, valve V, and rod C D, all as applied to an oiler or oil-can, in the manner described, and for the purposes set forth.
